This is the monitor in my Night Driver. It looks original, and history states that Atari used some of these monitors in their early B&W games. So I thought I would give info on it, as I was servicing it. It was working fine, but I at least wanted to service some of the POTS, check the B+ and recap it as the original NICHICON caps were on there and some were dated Feb of 74. 51 years and still going! That's a good cap manufacturer.

Anyways here goes:

Cap Kit:
C1 (Filter Cap): 1500uf @100v
C101: 22uf @ 25v
C102: 22uf @ 25v
C103: 10uf @ 25v
C106: 100uf @ 25v
C110: 22uf @ 25v
C119: 47uf @ 50v
C124 (axial): 47uf @ 50v
C126 (axial): 5 uf @ 150v (I replaced with 4.7uf @ 160v)
C134: 40uf @ 100v (Mine tested at 47uf so I replaced with 47uf)
C136: 1uf @ 50v
C141: 10uf @ 25v
C142: 4.7uf @ 160v

I checked the B+ at F101 and it should be 55 volts. (Red lead on F101 tab. Black lead on metal frame)
The tube it is hooked up to is a 22VATP4.

Pics are attached. I am getting a schematic soon and will upload it here. Any information in regards to this monitor should be added here. If I am incorrect with any info or there already is a repository of information, please don't be afraid to update.

Thank you! - Pat

I literally just found one of these in my workroom, was wondering what is was!

If you've found the schematics please post.
 
Yes I have it I'm sorry

it's I think it's a little bit bigger than eight and a half by 11 so I may have to like cut the image in half or whatever
 
So here's an image of mine. Its not tagged as to which machine I pulled it from :mad: which suggests a machine that had to be parted. My Night Driver has an M7000 so not that.

@PinFixin , any further data on which machines may have had these? I can find a manual for the TD-23, which came in a case, but not the TG 23.
 
Attached. I'll try to stitch together the images to make it nicer, unless yours is already like that.

No, I actually didn't do any research on which games had them, just how to service.

What's interesting is, and I will post impedance, is the ball brothers and my tec TM 623 use the same tube. So if the yoke is the same, I would theorize the chassis' are interchangable.

Thanks! Looks like they fit together as below. Couple of parts arent clear but I should be able to fill in from looking at the chassis itself.

This was pulled from a Death Race or Demolition Derby.

EDIT: Verified as pulled from a Chicago Coin 'Demolition Derby'. My Death Race has an XM-702.
